UNITED STATES PATENT OFFICE,

H. H. WELCH, OF ATHENS, OHIO.

FIRE-PLACE HEATER.

Specification forming part of Letters Patent N0. 119,325, dated August 8, 1865. u

.part of this specification, in which- Figure 1 represents my heater within a fireplace. Fig. 2 is a transverse vertical section taken on the line a; of Fig. 1.

Similar letters of reference indicate corresponding parts.

The object of this invention is to save a large amount of the heat that is now lost when fuel, is burned in fireplaces; and it consists in the heater is to be constantly supplied with freshair, which air, after being heated,is discharged through suitable conveyin g-pipes and registers to any part of a house.

A designates the heater. It is made of castiron or other suitable material, and of' such a size that it may be received within the tireplace where it is to be used without obstructing the fire. The back wall of the tire-place should have a recess to let the back part of the heater set in it alittle distance, .the rest of the heater (the front of it) protruding into the iirespace.

G is a pipe leading from the lower part of the heater, and which may connect with any suitable pipe opening without the house into the open air. Through the pipe G fresh air will pass into the heater.

B is a pipe leading from its upper part, and

which may connect with. any suitable pipe or pipes leading to the various apartments of the house. Through this pipe B the heated air is permitted to pass into such connecting-pipes. The pipe B should be larger than the pipe C,

because the air will be greater in volume aft'er it is heated.

The heater is ina-de irregular in form,having projections D and recesses F for the purpose of increasing the extent of its surface without enlarging itsV general dimensions. It has also projections E on its top and bottom. By giving the heater such a form the surface exposed to the'tireand heat ofthe ire-placeis increased.

The heater is not to be set snuglyr against the sides of the recess in the tire-place, but it should be clear therefrom, so as to let the products of combustion and hot air ascend on all sides ol it. The heater may` also be raised afew inches above the level of the grate or hearth 5 but the fuel supplied to the tire-place Vmay bc allowed to reach up to and around the front of the heater.

My invention will be the means of saving fuel, since one or more apartments besides that where the tire-place is situated can be coinfortably warmed with the fuel burned in such tire-place alone. t

I claiin as new and desire to secure by Letters Patent- As a new article of manufacture, the iireplace heater A, constructed as herein shown and described-that is to say, with the projections D E, recesses F, and pipes B C-t'or the purpose explained.
